The Westinghouse 11000 Peak Watt Dual Fuel Portable Inverter Generator stands out with its impressive power output, delivering 9000 running watts and 11000 peak watts on gasoline, and slightly less on propane. This makes it highly capable for residential use, particularly for those in need of reliable backup power. The remote electric start feature with a key fob adds convenience, especially during adverse weather conditions, while the push button and recoil start provide additional starting options.

Fuel efficiency is commendable with a 9.8-gallon tank offering up to 17 hours of runtime. This, coupled with its dual-fuel capability, provides flexibility and longer operation times. However, its weight at 187.4 pounds might affect portability, which could be a drawback for some users seeking a more mobile solution.

Safety features are robust, including a CO sensor and automatic low oil shutdown, ensuring safe operation. The generator is equipped with standard outlets, including transfer switch ready ones, all protected with rubber covers, enhancing safety further. The low Total Harmonic Distortion (THD) makes it safe for sensitive electronics, a major plus for households relying on electronic devices.

Despite its strong performance and features, the size and weight make it less ideal for those who prioritize easy transportation. It's suitable for those who can accommodate its bulkiness or plan to keep it stationary. The generator meets EPA compliance and comes with a 3-year limited warranty, backed by a solid customer service network, providing peace of mind regarding reliability and support.
